Manual meter reading is a tedious task that often fails to identify periods of wasteful consumption. Automatic Meter Reading (amr) systems are affordable technology solutions, which turn idle meter assets into data workhorses, allowing energy managers to focus their time on managing and reducing consumption.
The Carbon Trust state that savings of 5-20% are regularly achieved through the installation of amr systems and therefore they are part of the governments ECA scheme.
There are three main technologies commonly used for Automatic Meter Reading systems:
- Low power radio
- Power line
- GSM
Each technology has advantages and disadvantages. Selection is largely influenced by site specific limitations, potential number of sub-meters and physical meter locations.
Most modern meters use a frequency pulse output as a common protocol, that allows consumption (meter readings) to be remotely read and time logged by the connected amr device every 30 minutes.
The meter readings are then either downloaded immediately, hourly, daily or monthly depending on amr device type and then imported into the data analysis software.
